Enhancing Precise Perioperative Risk Surveillance: Validation of Submaximal Cardiopulmonary Exercise Testing to Usual Care for Detection of Myocardial Injury After Noncardiac Surgery
The goal of this clinical trial is to learn whether physicians can associate evidence of myocardial injury after surgery with findings obtained from submaximal cardiopulmonary exercise testing. The main questions are: Is detection of postoperative myocardial injury with submaximal cardiopulmonary exercise testing superior to using usual care? And which submaximal cardiopulmonary exercise testing measure is better? Participants will undergo evaluation with a short submaximal cardiopulmonary exercise test, then undergo surgery. Myocardial injury will be measured on postoperative days 0, 1, 2, and 3 (during and up to 3 days after surgery). These results will analyzed by comparing it to findings from the submaximal cardiopulmonary exercise test. If there is a relationship, this will help anesthesiologists and surgeons assign certain treatments that may reduce the risk of developing myocardial injury after surgery.
